I just received an email. I know they received my RPRF. you only need to pay it online (https://eservices.cic.gc.ca/epay/welcome.do?lang=en) , then you will get a pdf file to demonstrate that you have paid the RPRF, then open the link they gave you (https://secure.cic.gc.ca/enquiries-renseignements/canada-case-cas-eng.aspx), then write several words to tell them that you have paid the RPRF online, then input your UCI........., the last step is to upload that pdf file. OK , finish, wait wait.............you will get a reply many days later..
The email is :
